Another abstract view of southern Arizona deserts, while flying on my way to Tucson from Dallas. I don’t know exactly what kind of surface is this, but it looks like the bottom of a dry lake. I am always impressed by the invariance of scale in these geometrical patterns: if I didn’t know that this was shot from the window of an airplane I could have been easily fooled into thinking that these cracks formed in a dry pothole or old paint. Most of physical laws are in fact not invariant with scale, but the one regulating surface tension and the formation of cracks are apparently scaling very well on several orders of magnitudes in size. Did you know that when two cracks intersect they always do that crossing each other with a 90 degrees angle?
If you would like to see more abstract patterns based on aerial photos, have a look at the
geoabstract category: you may be interested in some photos I posted a few months ago shortly after starting this blog.
